30 best defensive prospects -- 1 for each team

January 18th, 2019

MLB Pipeline recently unveiled its annual All-Defense Team, but there were only so many spots to fill. It made us realize there were so many outstanding defenders across all 30 organizations.
Evaluating defense is still very much subjective, with metrics measuring fielding still imperfect. Still, each system has glovework that stands out more than others, and we considered many to present one best defender from each organization.
American League East
Orioles: Cadyn Grenier, SS, No. 9
Grenier's stellar glovework at shortstop was key in helping Oregon State win the 2018 College World Series, and in the process, he established himself as one of the best defensive prospects in the Draft before going to the Orioles as the No. 37 overall pick. With good hands, plus arm strength and plenty of range, Grenier has all the ingredients needed to stick at the position long term.
Red Sox: Bobby Dalbec, 3B,No. 6
Dalbec has always possessed a strong arm and has worked hard to improve his agility and range at third base, with several Red Sox officials rating him as a plus defender and scouts outside the organization grading him more as solid. He also owns prodigious raw power and ranked second in the Minors in extra-base hits (70) and RBIs (109) last year, and fourth in homers (32).
Yankees: Estevan Florial, OF, No. 1 (MLB No. 45)
Florial has some of the best all-around tools in the Minors, with well-above-average raw power, speed and arm strength. He continues to improve as a center fielder, projecting as a plus defender, and has an exceptionally strong arm for the position.
Rays: Lucius Fox, SS, No. 9
While there's no shortage of standout defenders in the highly athletic Rays system, Fox, a top-flight athlete with plus-plus speed, could be the best. He's played shortstop exclusively as a pro and committed 15 errors in 105 games last season while reaching Double-A at age 21. His athleticism makes him an electrifying defender, and he has the requisite physical tools to remain at the position for the long haul.

Blue Jays: Kevin Vicuna, SS, unranked
The Blue Jays felt so good about Vicuna's defense in 2017 that they had the then-19-year-old handle shortstop duties for Class A Advanced Dunedin from April 23-June 1, even though Vicuna previously had never played above the Rookie Gulf Coast League. He's an athletic and, at times, flashy defender, with quick, twitchy hands that help him absorb anything hit his way and a quick release that causes his average arm strength to play up across the infield.
AL Central
White Sox: Nick Madrigal, 2B, No. 5 (MLB No. 49)
The White Sox may try Madrigal at shortstop, because he has the hands and actions to thrive there, but his average arm makes him a better fit at second base. With his quickness and instincts, he could be a Gold Glove Award winner at the keystone, and he also rated as the best pure hitter in the 2018 Draft, where he went No. 4 overall.

Indians: Eric Haase, C, No. 27
Haase reached the Majors for the first time late last season, seven years after the Indians took him in the seventh round of the 2011 Draft. Though he's blossomed on both sides of the ball during the past two seasons, it's been Haase's defensive gains that have helped him climb the Tribe's depth chart. After throwing out 37 percent of attempted basestealers in 2017, Haase improved that mark to nearly 49 percent in '18 (33 of 68).
Tigers: Jake Rogers, C, No. 12
The Tigers got Rogers as part of the deal, and in Rogers' first full season with the organization, he cemented himself as the game's best defensive catching prospect, earning a spot on MLB Pipeline's All-Defense Team for the second year in a row. He threw out 55.6 percent of potential basestealers in 2018, upping his career rate to 48.5 percent.
Royals: Sebastian Rivero, C, unranked
M.J. Melendez is very athletic for a catcher and has a chance to become a plus defender with an arm to match. Yet South Atlantic League managers rated Rivero, his teammate at Lexington last summer, the low Class A circuit's best defensive backstop in a Baseball America survey last year. The Royals liken Rivero to a young , and in addition to his physical ability, Rivero also draws raves for his leadership skills, intelligence and work ethic.
Twins:Gilberto Celestino, OF, No. 14
Signed by the Astros for $2.5 million in 2015, Celestino made his United States debut in '17, then got dealt to the Twins in the trade last season. He's drawn comparisons to Albert Almora Jr. for his instincts in center, and coaches in Elizabethton feel he's one of the best defenders they've ever seen.
AL West
Astros: , OF, No. 15
Straw has double-plus speed that gives him tremendous range in center field, where his plus arm also stands out at a position not noted for strong throwers. That quickness also plays well on the bases (he topped the Minors with 70 steals in only 79 attempts in 2018) and allows him to beat out hits (he led the Minors with a .358 batting average in '16).
Angels:Jordyn Adams, OF, No. 6
The Angels signed Adams away from playing football and baseball at North Carolina, and he immediately put his tools on display during his pro debut and during instructs. He's still raw, but the Angels feel he has elite range and the highest ceiling as a defender in the organization.
A's: Nick Allen, SS, No. 15
Allen was viewed by many scouts as perhaps the best defensive prospect available in the 2017 Draft, and he's done nothing to diminish that reputation after signing for more than double slot value as the A's third-round pick. There is no doubt among scouts that Allen can stick at shortstop. He's already a plus defender there, with outstanding range that leads to many highlight-reel plays and plus arm strength that allows him to make throws from all over the diamond.
Mariners: Evan White, 1B, No. 5
It's not often a first baseman is mentioned as one of the premier defensive players in the Minors, but that's the reality with White, who recently was named to the All-Defense Team. All signs point to him becoming a Gold Glove Award winner at the position, as he's athletic with outstanding footwork, a strong arm and plus range. His ability to pick throws is elite, and he makes every infielder on his team better as a result.

Rangers: Jose Trevino, C, No. 28
Trevino won Rawlings Minor League Gold Gloves in both 2016 and '17, before surgery on his non-throwing shoulder last July squashed any chances of a three-peat. He's an outstanding receiver and blocker, gets the most out of his strong arm with a quick release and accurate throws and also earns high marks for his ability to run a pitching staff.
National League East
Braves: Cristian Pache, OF, No. 6  (MLB No. 68)
Pache is generally considered to be the best defender in the Minor Leagues, leading our All-Defense Prospect Team. He has the speed and instincts to be a Gold Glove center fielder to go along with a right fielder's arm.

Marlins: Jose Devers, SS/2B, No. 13
The cousin of Red Sox third basemen , Jose was acquired by the Marlins last offseason in the blockbuster trade that sent to the Bronx. While he doesn't have his cousin's offensive profile, Devers is a far superior defender, with the soft hands, slick footwork and strong arm needed to be a big league shortstop. He showcased his defensive prowess last season, committing only seven errors and posting a .971 fielding percentage as an 18-year-old in full-season ball.
Mets:Andres Gimenez, SS, No. 1 (MLB No. 55)
The shortstop on our All-Defense Team, Gimenez reached Double-A in 2018 as a teenager. While he needs to add strength offensively, he has everything he needs to play shortstop defensively in the big leagues. He has plus hands, range and the internal clock to allow him to slow the game down.
Phillies:Luis Garcia, SS, No. 14
Signed for $2.5 million in July 2017, Garcia had a tremendous debut in the Gulf Coast League in '18 on both sides of the ball. He has a strong arm to go along with terrific hands and feet, and speed that gives him excellent range to stay at shortstop long term. He's only going to get better as he matures.
Nationals: Victor Robles, OF, No. 1 (MLB No. 4)
Revered as one of the top defenders in the Minor Leagues and a member of MLB Pipeline's All-Defense Team, Robles has game-changing abilities in center field. His near top-of-the-scale speed gives him range for days in center field, and he's made strides in improving both his reads and routes in the past two years. His plus-plus arm is among the strongest in the Minors, and he totaled 29 outfield assists from 2016-17 before an injury-plagued campaign in '18.

NL Central
Cubs: Miguel Amaya, C, No. 1 (MLB No. 87)
Amaya's defensive ability and makeup led the Cubs to sign him for $1.25 million out of Panama in 2015, and he continues to impress even though he has been pushed aggressively in the Minors. His aptitude to frame and block pitches is advanced for a teenager, and his arm strength has improved to at least solid and plays up because of his quick transfer and accuracy.
Reds:Mike Siani, OF, No. 9
The Reds' fourth-round pick got first-round money to sign because of his all-around tools. But his defensive skills have long stood out, and he might have been the best defensive outfielder in the 2018 Draft class, with the ability to cover a ton of ground in center and an arm that allowed him to throw low-90s fastballs from the mound in high school.
Brewers: Payton Henry, C, No. 11
A sixth-round pick in 2016 who signed for nearly twice his slot value, Henry threw out nearly 44 percent (46 of 105) of attempted basestealers and had only six passed balls in his first full season. A quick release and a strong, accurate arm help Henry to combat the running game, and evaluators have been impressed with how he's developed a receiving style that utilizes his big, athletic frame. Henry is also praised for his energy and leadership skills.
Pirates:Ke'Bryan Hayes, 3B, No. 2 (MLB No. 48)
Hayes was the third baseman on our All-Defense Team, and for good reason. He entered pro ball as one of the better defenders at the hot corner, but he's gotten even better as he's committed himself to his conditioning, adding to his agility and range to make him the best in the Minors at the position.
Cardinals:Delvin Perez, SS, No. 28
The Cardinals' first-round pick in 2016 has had trouble finding any traction offensively, but there are no concerns about his defensive chops. He gets plus grades on his arm and his overall fielding, thanks to a plus arm when he needs it, above-average hands and plus speed that helps him cover a lot of ground.
NL West
D-backs: Geraldo Perdomo, SS, No. 21
Perdomo's United States debut in 2018 was solid all-around, and he even earned a promotion from the Arizona Rookie League to the Pioneer League in the process. Tall and rangy, the teenager has shown the tools to stay at shortstop long term with outstanding range, actions and hands to go with a strong arm.
Rockies: Yonathan Daza, OF, No. 18
Thanks to his plus speed and fine instincts, Daza covers a lot of ground in center field, and he possesses a plus-plus arm that stands out at his position. He's also a career .310 hitter who won the Class A Advanced California League batting title in 2017 with a .341 mark.
Dodgers: Will Smith, C, No. 5
An outstanding athlete for a catcher, Smith has already shown that he's capable of playing third base and filling in at second. He has very soft hands and impressive agility, making him a fine receiver and framer, and he has a solid arm that plays better than that because of his fast footwork.
Padres: Buddy Reed, OF, No. 13
A member of MLB Pipeline's All-Defense Team, Reed's 70-grade speed and long, gliding strides allow him to cover huge swaths of territory in center field -- and he showcased that with his catch in last year's SiriusXM All-Star Futures Game. Reed also has a strong arm and recorded 12 outfield assists in 2018, surpassing his combined total from his first two seasons.

Giants: Joey Bart, C, No. 1 (MLB No. 23)
The No. 2 overall pick in the 2018 Draft, Bart draws more attention with his bat, but his work behind the plate is impressive as well. He has improved markedly since high school, when scouts wondered if he could stay at catcher, enhancing his agility and receiving and improving the accuracy of his strong arm.
